• Proven end-to-end ownership, independence, and ability to turn ambiguous requirements into working solutions.
• Strong product mindset, proactive problem-solving, and the ability to manage multiple priorities in a fast-moving environment.
• Willingness to work across technical boundaries rather than limiting yourself to backend development.
• Strong communication skills and the ability to collaborate effectively in English.
   

Nice to Have

• Experience in fast-paced product development environments.
• Familiarity with REST APIs, event-driven architectures, and asynchronous processing

ScrumLaunch is a software development company supporting fast-growing US startups across various industries, with locations in Los Angeles, CA, and Portland, OR. We partner with startups by embedding product and engineering teams directly into their core operations.

For this role, we are looking for a Senior Product Manager to own consumer-facing mobile and scheduling products from concept through launch and iteration. This role is ideal for a PM who has built B2C products used by real consumers on a daily basis, has deep familiarity with booking/scheduling/availability logic, and knows how to design transactional flows (booking, payment, cancellation, membership) that feel effortless even when the underlying business rules are complex.

You will be responsible for defining the end-to-end member/user experience across mobile and web surfaces, working closely with Engineering, Design, and Data teams to ship features that drive engagement, retention, and conversion. This includes designing booking and scheduling logic, membership/eligibility rules, multi-location or multi-tenant product behavior, and notification/lifecycle flows. You will also be expected to identify where AI agents and automation can meaningfully improve the consumer experience — from personalized recommendations to proactive, agent-driven suggestions — while keeping the product simple and trustworthy for end users.

This is a hands-on, high-ownership role for a PM who thinks in terms of user journeys and funnels as much as backlogs, and who is comfortable managing the operational complexity that comes with real-time availability, payments, and multi-party bookings.

Requirements

Must Have

• 5+ years of Product Management experience, with a strong track record of building and scaling B2C products used directly by consumers.
• Proven experience owning mobile applications (iOS and/or Android) from requirements through release, including app-store considerations, mobile-specific UX constraints, and cross-platform prioritization.
• Direct experience with scheduling, booking, appointment, calendar, or resource-availability systems — including handling double-booking prevention, real-time availability, cancellation/refund policy logic, and multi-party transactions.
• Experience designing and documenting complex consumer transactional workflows (e.g., booking + payment + split payment, membership eligibility, multi-step checkout).
• AI Agent orchestration experience — practical experience scoping, designing, or delivering AI-agent-driven features such as personalized recommendations, proactive notifications, conversational assistants, or automated matching/suggestion engines.
• Strong product analytics skills: comfortable defining KPIs, working with funnels/cohort data, and using data to prioritize the roadmap.
• Experience managing products with multi-location, multi-tenant, or multi-market complexity (e.g., different pricing, policies, or configurations per location).
• Strong cross-functional collaboration skills across Engineering, Design, QA, and Marketing/Growth.
• Strong documentation skills: PRDs, user journeys, functional requirements, and acceptance criteria for consumer-facing features.

• Experience working within Agile delivery environments, including backlog prioritization and release planning.

   

Nice to Have / Would Be a Plus

• Experience with membership, subscription, or loyalty program products (tiered pricing, lifecycle automation, points/rewards).
• Experience with CRM or lifecycle marketing automation (segmentation, triggered campaigns, churn/win-back flows).
• Experience migrating consumer users off a third-party booking/scheduling vendor onto an owned platform.
• Familiarity with payment processing integrations (e.g., Stripe or equivalent), including split payments and refund logic.
• Experience with social or community features layered on top of a transactional product (e.g., matchmaking, groups, activity feeds).

• Background in hospitality, fitness, wellness, sports, or other appointment-driven consumer verticals.

   

What Makes Someone Successful in This Role

• Thinks like a consumer first — obsessive about reducing friction in booking, payment, and everyday usage flows.
• Comfortable translating messy, real-world operational rules (cancellation windows, eligibility, multi-location pricing) into clean, scalable product logic.
• Data-driven: uses analytics and user behavior to prioritize, not just stakeholder opinion.
• Strong at balancing near-term feature delivery with long-term platform scalability (e.g., supporting new locations/markets without re-architecture).
• Pragmatic about where AI adds real consumer value versus where it adds complexity without benefit.
• Effective at aligning Engineering, Design, and Growth around a shared view of the user journey.
• Comfortable owning ambiguity in fast-moving, growth-oriented environments.

• Detail-oriented about edge cases — the PM who catches the double-booking, the abandoned-cart, or the mid-cycle proration case before it ships.

   

Responsibilities

• Own the end-to-end roadmap for consumer-facing mobile and web product experiences.
• Define and document booking/scheduling logic, including availability rules, eligibility, cancellation/refund policy, and multi-party or split transactions.
• Translate business and operational rules into clear PRDs, user journeys, functional requirements, and acceptance criteria.
• Partner with Engineering and Architecture on technical feasibility for real-time availability, payments, and multi-location/multi-tenant logic.
• Scope and define AI-agent-driven features (e.g., personalized recommendations, proactive suggestions, automated matching) with clear success criteria and guardrails.
• Manage backlog prioritization, sprint planning, refinement, and release planning for the consumer product.
• Define and track product KPIs (conversion, retention, engagement, booking completion rate) and translate insights into roadmap priorities.
• Collaborate with Design on user flows, wireframes, and usability validation for mobile-first experiences.
• Coordinate cross-functional teams (Engineering, QA, Design, Growth/Marketing) through discovery, build, and launch.
• Own membership, loyalty, or lifecycle feature definition where applicable, including automation of renewal/upgrade/downgrade flows.
• Identify and resolve dependencies, risks, and blockers across mobile, backend, and third-party integration workstreams.
• Facilitate product demos, stakeholder reviews, and go-to-market readiness checkpoints.
• Maintain roadmap documentation, decision logs, and product performance reporting.

• Continuously iterate on the product based on usage data, user feedback, and market/competitive analysis.

   

Tools

• Jira, Linear, or similar project management platforms
• Notion, Confluence, or similar documentation tools
• Figma
• Slack
• GitHub, Cursor, and agentic development tooling
• Product analytics platforms (e.g., Amplitude, Mixpanel, or equivalent)

• Payment and scheduling infrastructure familiarity (e.g., Stripe, calendar/availability engines) 

   

Cooperation terms

• B2B cooperation under a Consulting Agreement
• 12 days of Paid Time Off per year
• 5 days of Medical Time Off per year
• 3 paid holidays per year
• Psychologist Consultations for mental well-being
• Professional Development Budget — courses and conferences
• English lessons
